( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Thanks for the reply. I am using perl version 5.8.4 which you had suggested earlier.

I have been playing with the code...but could not understand:

last if keys %$lookfor == grep defined, values %$lookfor; $line =~ $_ and $lookfor->{ $_ } = $line for keys %{ $lookfor +};

I understand it means that for keys %{ $lookFor }, if $line =~ $_, then $lookFor->{$_} = $line...but was not sure what if keys %$lookfor == grep defined, values %$lookfor meant.

Also, had a little trouble understanding what the following means... (what does < do ?) :

sleep 1 while grep( $_, @dones ) < @cmds;

I understood that when the keywords are found, kill 1, $pid immediatly kills the pid for that particular thread, but does it also stop the other 3 threads that are still going on?

Thank you.

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
